Is your shorter PCH as easy to shoot accurately as your longer PSA or PMA?  I know your limbs could be the same length with the shorter riser but I think the PCH limbs have a narrower profile and you have less mass in the riser.

I shoot both, and see no difference.  I am probably not the best source to answer this thread because my PSA is 60", and my PCH is 58",so the limbs are the same length.
But for what it is worth; I get the same feel with my PCH, and have a 2" shorter advantage.

Anyone else shoot a PCH?

I have both PSA and PHC at 60", I draw 30". The PCH is slightly smoother due to the longer working limbs. The PSA is more stable due to the extra riser weight. Now.... this is really spliting hairs. I also have a PSA 62" that feels like a cross between the two. If I could only own one widow it would be the PSA 62", because I just shoot longer bows better. The reason I have the 60" bows is for use in std height DB blinds. I should probably just buy the taller DB blind, then I would only need one length bow LOL. Either way you can't go wrong. Good luck, Glen
